SINK-STOPPER.

Specification of Letters Patent.

Patented Dec. 16,1913.

Application filed October 18, 1913. Serial No. 795,898.

To all whom it may concern:

Be it known that I, GEORGE A. Cori of the city of Montreal, in the Province of Quebec, Dominion of Canada, a subject ofthe King of Great Britain,'l1ave invented certain new and useful Improvements in Sink-Stoppers; and I do hereby declare that the following isa full, clear, and exact description thereof.

This invention relates particularly to means for closing the discharge from kitchen sinks which are not usually provided with stoppers; and it has for its object to enable the water to be held temporarily in the sink for washing purposes.

My improved device consists of an india rubber device of substantially inverted saucer form with exterior and interior bosses and the edge of its periphery extended to form a flat foot, the bosses having the shank of a hook inserted therein, while one side of the device has a small external boss to indicate the side of the hook at which the opening is located. Forfull comprehension, however, of my invention reference must be had to the accompanying drawings forming a part of this specification, in which similar reference characters indicate the same parts, and wherein:

Figure 1 is a transverse vertical sectional view of my improved sink stopper before being set in place; Fig. 2 is a similar view set in place; and Fig. 3 is. also a similar view illustrating the manner of removing the stopper; and Fig. 4 is a plan view partly broken away.

An india-rubber section of inverted saucer form is indicated at b. It'is formed with an exterior knob c to serve as a thumb hold located centrally of the device and having in juxtaposition therewith an interior boss (Z with rounded end 6 extending to within close proximity of the level of the rim. The hook f having a long shank g with barbs k and retaining disks k i rigidly secured thereto, located in the boss and knob with the hook end pointed and projecting to the same plane as the rim of the device before the latter is set in place. The body of the device is relatively thick in the middle and tapered in cross-section to the rim which is formed to extend outwardly at a comparatively sharpangle and present a flat annular foot is such foot beingv demarcated by a circumferential incision p in order to cause it to bend outwardly when the device is pressed into place. On the same side of the device as faced by the opening in the hook I locate a small boss m to indicate in which direction the hook faces.

When setting the stopper in place it is placed over the drain connection and pressed downwardly, the effect being that the rim is bent at the line of junction between the foot and the body of the stopper, and such foot is set flat on the surface of the sink surrounding the drain connection and the hook will trip over one of the bars of the grating and engage beneath it thus holding the device in place. In order to release the stopper the thumb piece a is pressed in the direction of the arrow 1, Fig. 3, and simultaneously the small boss m is pressed in the direction of arrow 2 depressing the knob laterally and throwing the boss at in the direction indicated by arrow 3 thus releasingthe hook.

It is necessary .to embed the shank of the hook in the rubber when in the mold in order that it may be firmly held in place, and the foot must be so disposed as to rest at an acute angle to the bottom of the sink before being set.

It is preferable to make the side of the stopper having boss m thereon slightly heavier and consequently less flexible than the opposite side in order to insure the yielding of such opposite side and the lateral movement of the boss (Z in that direction when the boss m is depressed. The disks h prevent longitudinal displacement of the- What I claim is as follows 1. A sink stopper consisting of an indiarubber device of inverted saucer form with an alined exterior knob and interior boss, the boss extending to a point in close proximity to the plane or level of the rim of the device and a hook having a shank extending upwardly into'the boss and knob.

2. A sink stopper consisting of an indiarubber device of inverted saucer form with an alined exterior knob and interior boss, the boss extending to a point in close proximity to the plane or level of the rim of the device, and a hook having a shank extending upwardly into vthe boss and knob, and the rim of the said device being formed with a fiat foot.

3. A sink stopper consisting of an indiarubber device of inverted saucer form with an alined exterior knob and interior boss, the boss extending to a point in close proximity to the plane on level of the rim of the device, a hook having a shank extending upwardly into the boss and knob, the body of suchdevice having an exterior boss indicating the direction-in which the hook faces,

and the rim of the said device being formed with a flat foot.

4. A sink stopper consisting of an indiarubber device of inverted saucer formwith an alined exterior knob and interior boss, the boss extending to a point in close pronimity to the plane or level'of the rim of the device and a hook having a shank extending upwardly into the boss and knob and having a retaining disk rigidly secured for preventing longitudinal displacement of such hoo 5. A sink stopper consisting of an indiarubber device of inverted saucer form having a hook located at the. middle of the interior thereof and the body of such device having an exterior boss indicating thedirection in which the hook faces and the portion of the body contiguous tothe boss'of increased thickness.

In testimony whereof I have signed my name tothis specification in the presence of two witnesses.
